2-(Diphenylphosphino)-N,N-diethylbenzamide CAS 143024-49-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(Diphenylphosphino)-N,N-diethylbenzamide.

2-(Diphenylphosphino)-N,N-diethylbenzamide (CAS 143024-49-1), molecular formula C23H24NOP and molecular weight 361.42 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C23H24NOP, 2-(Diphenylphosphino)-N,N-diethylbenzamide contains a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 361.42 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
